Posted By Discussion Topic: Oil brand & type, '36 -- page: 1 2     johnpoly 02-25-2010 @ 4:19 PM reply profile send p.m. Member Posts: 39 Joined: Oct 2009 I have been putting 30wt non-detergent in my '36. When the engine is hot the oil pressue goes to zero when idling. It goes back up to about 10 lbs when running. I have seen that many of you use 20wt-50wt oil. Would this be better for me at idle? Thanks for guidance, John 37RAGTOPMAN 02-25-2010 @ 4:48 PM reply profile send p.m. Senior Posts: 1958 Joined: Oct 2009 HI you might want to try a mechanial gauge,just to see if the original gauge is working correctly,it might be off a few pounds, giving you a low pressure reading, this is a concern,so no engine damage, you could put a high pressure oil pump in, I did this in my 37 85 hp engine, and now reads 20-30 pds hot, and 50 going down the road,I still use the original guage, and you could go to 20-50 PENZOIL,CASTROL, or a straight weight oil, HARLEY DAVIDSON SELLS 50 w and I think this would also work well in these old engines, hope this helps,37 RAGTOPMAN ford38v8 02-25-2010 @ 7:07 PM reply profile send p.m. Senior Posts: 2758 Joined: Oct 2009 John, the 20/50 should work well for you, but my choice is 10/30, as I don't want such a thick oil, and don't need the extra phosphorous. (Our old Fords haven't the phosphorous [zinc] problem that some early overhead valve engines have.) The much bigger issue here is the use of detergent versus non-detergent oil. There is no reason for any engine to use non-detergent oil today, and every reason to use detergent.

You can find 15W-40 at most Walmarts. As my friend, Alan, points out, non-detergent oil belongs only in oil cans. Too many newcomers to the old Ford hobby obsess over oil pressure. It is a rare engine that shows much, if any, oil pressure when at hot idle.

I haven't seen the spec sheet on Rotella lately but chances are that it has no more zinc than anything else. The best oils that contain high levels of zinc, in my opinion, are CCMO, VR-1 and Mobil 1. wmsteed 02-26-2010 @ 10:58 AM reply profile send p.m. Senior Posts: 613 Joined: Oct 2009 I don't even use non-detergent oil in my oil cans. When i pore the contents out of an oil container into an engine, etc. I turn the empty container upside down into an old 2gt oil can. After the oil container is completed drained of any oil residue I discard the plastic container and cover the 2qt can. From time to time I transfer the oil from the 2qt into a sealed container that I use for my small oil cans. It is truly amazing how much oil can be high-graded out of empty oil containers.

Plus, here is another guy who emailed them and got this reply: "The latest rumors about Rotella had me thinking we were down to using high dollar racing oil. Found a Rotella web site, emailed a question, took a nap, got a reply. Sometimes its your day. Here is question and reply; I have heard that Rotella T CI-4 is being phased out, replaced by CJ-4. Is the ZDDP content being reduced? If so, by what percentage, or what will the PPM of ZDDP be with the new oil if its not a trade secret? The hotrod guys are dying to know, we've all been using Rotella due to flat tappet camshaft break in problems using the new oils without the ZDDP additives. Here is his reply: We still sell Rotella T 15w-40 CI-4 in 55 gallon drums, but not in smaller packages. It has approximately 1400 ppm zinc. You can buy this from a sh*ll lubricants distributor. Since Oct. 15,2006 all small packaging has been Rotella T with triple protection 15w-40 CJ-4 and it has approximately 1200 ppm zinc. This is 50% more zinc than current passenger car motor oils which contain approximately 800 ppm zinc. Passenger car motor oils had approximately 1200 ppm zinc prior to 2001. In 2001 the zinc was reduced to 1000 ppm and in 2005 reduced again to the current 800 ppm. Thus, the new Rotella T with triple protection 15w-40 CJ-4 has the same zinc content that passenger car motor oils had in 2000 before the current problems with flat tappets began. However, zinc compounds are not the only additives that can reduce wear. We were able to reduce wear approximately 50% with the new Rotella T with triple protection 15w-40 CJ-4 formulation. This is from a staff engineer in Houston, Texas."

Dan MTLott 02-26-2010 @ 1:11 PM reply profile send p.m. Member Posts: 38 Joined: Oct 2009 " ... Valvoline Racing 40. Any thoughts?" Got to be great oil. I am certainly not an expert on oil, and I do not know how you're using it. But, multi-grade oil is my choice for general usage; it simply oils up faster on startups as it is designed to do. The drawback on multi-grades is that it takes "polymers" to make them work. If the polymers wear out somehow, like in racing maybe, then I'm not sure what weight you'd have. I use Rotella in my flatheads and Mobil 1 in my aging modern vehicles. BUT, man, there are so many good oils to choose from. (I'm more worried about finding a replacement transformer for my Sun machine. Got one?) supereal 02-26-2010 @ 2:09 PM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 Bob Masters has them. 800/385-5811. e-mail: Rmasters3@insightbb.com Note on oil: Our supplier confirms that Rotella contains adequate zinc to protect cams, etc. The problem with diesels is the "new" fuel which has reduced lubricity causing rapid injector pump wear. We have replaced two pumps for customers so far this year. In over 50 years in the business, I have yet to see a flat original cam in an old Ford. I just replaced my '04 Lexus with an '10, and the required oil is full synthetic 0W-20. They claim 15,000 mi between changes, or yearly. When Toyota increased oil change interval to 7,500 they had to buy a bunch of new engines due to oil jelling. I wonder what changed their mind?
